python - 刮 1a. 10K 文件的风险因素

Question

我正在努力获得1a。每个 10-K 文件中的风险因素部分。我已经下载了文件并将它们保存为txt。文件。

```'/content/drive/My Drive/Colab Notebooks/10/BKR/1.txt'
'/content/drive/My Drive/Colab Notebooks/10/BKR/2.txt'```

因此，文件夹 10 包含几个子文件夹（如 10），每个子文件夹（如 BKR）包含几个 10-K 作为 txt 文件。

我尝试了下面的代码来获取 1a.Risk Factors 部分，但它失败了。如果你能分享你的意见，我会很高兴。

```import re
import os, os.path

PATH = '/content/drive/My Drive/Colab Notebooks/10/BKR'

conclusions = []
for file in os.listdir(path):
    with open(os.path.join(PATH, file)) as f:
        data = f.read()

    conclusion = re.search('1a: (.*?)([A-Z]{2,})', data).group(1)
    conclusions.append(conclusion)```

我得到的错误信息：

```
